July. (n. 542.) —This is identical with the pretty G. alienum 
described by Dr. Arnott and myself from Mr. Cuming's 
Chilian collections. We called it “ alienum,” from its 
being so extremely dissimilar from any other S. American 
Gnaphalium. It is equally unlike any North American 
one, having the habit of an Elichrysum, and the upper 
scales of the involucre bright rose-colour, the rest pale 
yellowish.
